1 Almost every home has a large stove or oven in it to cook food. But some houses have a small oven called a toaster oven. A toaster oven is a nice thing to have. If you are only cooking for one or two people, there are good reasons to use a smaller oven.2 A toaster oven uses less energy than a big oven. The toaster oven will help you use less electricity. This means you will save money on the electric bill. Try to use the toaster oven for small meals. It takes less energy to heat up the small space inside the toaster oven.3 One good thing about a toaster oven is that it cooks faster. But this can be a bad thing, too. If you aren't paying attention, the food could burn. This can happen quickly in the toaster oven. If the food cooks too long, it could start a fire. Cooking is the leading cause of house fires in the United States.
